Process for reverse gas flow in hydroprocessing reactor systems

摘要

A process for reverse gas flow to obtain high conversion, selective hydrotreating and product selectivity in hydroprocessing reactor systems is disclosed. In the integrated process, hydrogen recovered from a hydrotreating reactor is purified and used as a source of hydrogen for a hydrocracking reaction zone. Hydrogen recovered from the hydrocracking reaction zone is recovered without substantial cooling and used as a source of hydrogen for the hydrotreating reaction zone.
